Hello, I apologize if this has been suggested before, however, I did not see any mention of it in the forum. When using 3CX with Fanvil X5S phones and configuring 2 BLF buttons to be Q:IN and Q:OUT, there is no indicator on the phone to remind the user if they are logged in or out of the queue. The lights on the buttons configured for Q:IN and Q:OUT do not light up based on what mode the user has selected. Since our office does not have dedicated agents, they can forget if they are logged in or out of the queue. I checked with the Fanvil technical engineers and they indicated the 3CX system did not support subscribe call queue status, so they could not help on their end, so I thought I'd submit a request here. Thank you!
